Intel Core i5-14401E vs Intel Core Ultra 7 155UL Comparison

Where Each One Wins

The data splits these two processors into entirely different use cases. The Intel Core i5-14401E is a 6-core, 12-thread desktop part built for sustained multi-threaded workloads and high single-core responsiveness. Its benchmark scores are recorded in the database across Cinebench R15, R20, and R23, and it holds a 60th percentile ranking among all CPUs. The Intel Core Ultra 7 155UL, by contrast, has a 12-core, 14-thread hybrid design with a 15 W TDP, placing it in a power-lean segment. Its average benchmark score is listed as zero, and it has no recorded benchmark entries in the database, so its wins are structural rather than measured.

The Core i5-14401E wins where raw compute throughput matters. It posts a Cinebench R23 multi-core score of 18161 and a single-core score of 2564. Those are strong numbers for a desktop chip with a 65 W TDP. The Core Ultra 7 155UL wins where power efficiency and integrated graphics matter. It carries Arc Xe-LPG 64EU graphics, a much more capable integrated GPU than the UHD Graphics 730 found in the i5-14401E. It also supports DDR5 memory with a recorded bandwidth of 89.6 GB/s, and its 15 W TDP means it can fit into systems where cooling and power budgets are tight.

The use-case split is clear. The i5-14401E is for builders who want a conventional desktop CPU with high clock speeds, a mature socket, and proven multi-core performance. The Ultra 7 155UL is for compact or low-power desktop builds where the integrated GPU does heavy lifting and the CPU draws a fraction of the power.

Architecture Differences

These two chips come from different Intel lineages. The i5-14401E uses Raptor Lake architecture on a 10 nm process, with a die size of 215 mm². It fits the Intel Socket 1700 platform. Its cache layout is 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3. It supports both DDR4 and DDR5 memory in a dual-channel configuration, and it enables ECC memory. PCIe connectivity is Gen 5 with 16 lanes from the CPU.

The Ultra 7 155UL uses Meteor Lake architecture on a 7 nm process, and it fits the Intel Socket 1851 platform. Its cache layout differs substantially: 112 KB L1 per core, 2 MB L2 per core, and 12 MB shared L3. It supports DDR5 memory only, with the database noting that support depends on the motherboard, and it has a recorded memory bandwidth of 89.6 GB/s. ECC memory is not supported. PCIe connectivity is Gen 4 with 8 lanes from the CPU.

The core counts tell different stories. The i5-14401E has 6 cores and 12 threads, all of the same type. The Ultra 7 155UL has 12 cores and 14 threads, indicating a hybrid arrangement where some cores are efficiency-focused and do not add extra threads. The Ultra 7 also has a higher boost clock at 4.80 GHz versus 4.70 GHz for the i5, but a much lower base clock at 1.70 GHz versus 2.50 GHz. The TDP gap is massive: 65 W for the i5-14401E versus 15 W for the Ultra 7 155UL.

Integrated graphics differ as well. The i5-14401E uses UHD Graphics 730, a basic display-output solution. The Ultra 7 155UL uses Arc Xe-LPG 64EU, which is a significantly more capable GPU for media playback, encoding, and light gaming. The Ultra 7 also has a higher launch MSRP of $426, while the i5-14401E has no recorded launch price.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two CPUs, and the Ultra 7 155UL has no recorded benchmark scores at all. The comparison must therefore rely on the i5-14401E's measured results and the Ultra 7's architectural specifications.

The i5-14401E delivers a Cinebench R23 multi-core score of 18161. For context, its nearest rivals in the database include the Intel Core i9-10850K with an average score of 5240, a 0.2% difference, and the Intel Core i7-11700B with an average score of 5241, also a 0.2% difference. The i5-14401E outperforms the Intel Xeon E5-2699A v4 by 0.1% on average score. Its Cinebench R20 multi-core score is 7627, and its R15 multi-core score is 1830. Single-core results are equally solid: R23 single-core at 2564, R20 single-core at 1076, and R15 single-core at 258.

The Ultra 7 155UL has no benchmark scores to compare. What the data shows is a specification profile built for a different kind of workload. Its 12-core, 14-thread layout gives it more physical cores than the i5-14401E, but its 1.70 GHz base clock and 15 W TDP indicate that those cores are tuned for efficiency rather than peak throughput. Its 4.80 GHz boost clock does allow for bursts of speed when needed, but the sustained multi-core performance of the i5-14401E, reflected in its 18161 R23 score, is the kind of result the Ultra 7 cannot match without recorded benchmarks.

The i5-14401E also holds the advantage in memory flexibility. It supports both DDR4 and DDR5, while the Ultra 7 is limited to DDR5. The i5 supports ECC memory; the Ultra 7 does not. The i5 has PCIe Gen 5 with 16 lanes, while the Ultra 7 has PCIe Gen 4 with 8 lanes. These differences matter for system builders who need expansion capacity or error-correcting memory.

The Ultra 7 counters with its integrated Arc Xe-LPG 64EU graphics, which is a far stronger iGPU than the UHD Graphics 730. It also has a higher recorded memory bandwidth of 89.6 GB/s, though the i5 has no bandwidth figure recorded. The Ultra 7's 15 W TDP gives it a decisive advantage in thermals and power draw, making it suitable for passive or near-passive cooling solutions.

The Verdict

The data points to a simple conclusion. The Intel Core i5-14401E is the choice for anyone who needs measured multi-core performance, high clock speeds, ECC memory support, PCIe Gen 5 connectivity, and compatibility with both DDR4 and DDR5. Its benchmark scores are recorded and strong, with a 60th percentile ranking among all CPUs and an average benchmark score of 5253.

The Intel Core Ultra 7 155UL is the choice for anyone who needs a low-power desktop processor with a powerful integrated GPU. Its 15 W TDP is a fraction of the i5-14401E's 65 W TDP, and its Arc Xe-LPG 64EU graphics are in a different class from UHD Graphics 730. It also has more physical cores at 12 versus 6, and a higher boost clock at 4.80 GHz versus 4.70 GHz. The trade-offs are real: no ECC support, no DDR4 compatibility, fewer PCIe lanes, and no recorded benchmark scores in the database.

The i5-14401E is the safer pick for a conventional desktop workstation or gaming rig. The Ultra 7 155UL is the pick for a compact, power-efficient build where the iGPU handles graphics duties. Neither chip is unlocked for overclocking. Both are currently active in production.
